centos6.4 http dhcp nfs pxe kickstart 自動化安裝系統

1 環境準備

centos 6.4 x86_64 安裝圖形界面 以運行sysconfig-config-kickstart

yum install vim ntp man

yum groupinstall 「development tools」 「server platform development」 「desktop platform development」

關閉 iptables selinux

2 掛載鏡像文件

mkdir /media/cdrom

mount /dev/cdrom /media/cdrom

3安裝所須要的軟件包

yum install dhcp xinetd tftp-server nfs* httpd syslinux system-config-kickstart

4 配置dhcp服務器

cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

vim /etc/dhcp/dhcpd.conf

# option definitions common to all supported networks...    
option domain-name "example.org";    
option domain-name-servers 192.168.200.2;

default-lease-time 600;    
max-lease-time 7200;

# Use this to enble / disable dynamic dns updates globally.    
ddns-update-style none;

# If this DHCP server is the official DHCP server for the local    
# network, the authoritative directive should be uncommented.    
#authoritative;

# Use this to send dhcp log messages to a different log file (you also    
# have to hack syslog.conf to complete the redirection).    
log-facility local7;

next-server 192.168.200.131;    
filename="pxelinux.0";    
#No service will be given on this subnet, but declaring it helps the    
# DHCP server to understand the network topology.

subnet 192.168.200.0 netmask 255.255.255.0 {    
range 192.168.200.10 192.168.200.20;    
option routers 192.168.200.2;    
}

5 複製安裝系統須要的核心文件及光盤鏡像

cd /media/cdrom/isolinux/

cp boot.msg splash.jpg vesamenu.c32 /var/lib/tftpboot/

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

cd /media/cdrom/p_w_picpaths/pxeboot

cp vmlinuz initrd.img /var/lib/tftpboot/

mkdir /var/lib/tftpboot/pxelinux.cfg/

cp /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

6 編輯default文件

vim /var/lib/tftpboot/pxelinux.cfg/default

label linux    
menu label ^Install or upgrade an existing system    
menu default    
kernel vmlinuz    
append initrd=initrd.img ramdisk_size=8192 ks=http://192.168.200.131/ks.cfg

7 配置NFS 服務器

Vim /etc/exports

/media/cdrom 192.168.200.0/255.255.255.0 (ro,sync)

8 啓動httpd nfs xinetd tftp 服務

service httpd start

service dhcpd start

service rpcbind start

service nfs start

service xinetd start

chkconfig httpd on

chkconfig dchpd on

chkconfig rpcbind on

chkconfig nfs on

chkconfig tftp on

9 在圖形界面運行system-config-kickstart （過程略）

建立ks.cfg文件 移動到 /var/www/html

#platform=x86, AMD64, or Intel EM64T    
#version=DEVEL    
# Firewall configuration    
firewall --disabled    
# Install OS instead of upgrade    
install    
# Use NFS installation media    
nfs --server=192.168.200.131 --dir=/media/cdrom    
# Root password    
rootpw --iscrypted $1$fn7ZGte9$1am0UPE8lztKAmdZAGLMY1    
# System authorization information    
auth --useshadow --passalgo=sha512    
# Use graphical install    
graphical    
firstboot --disable    
# System keyboard    
keyboard us    
# System language    
lang en_US    
# SELinux configuration    
selinux --disabled    
# Installation logging level    
logging --level=info    
# Reboot after installation    
reboot    
# System timezone    
timezone Asia/Shanghai    
# Network information    
network --bootproto=dhcp --device=eth0 --onboot=on    
# System bootloader configuration    
bootloader --location=mbr    
# Clear the Master Boot Record    
zerombr    
# Partition clearing information    
clearpart --all  --initlabel

%packages    
@desktop-platform-devel    
@development    
@server-platform-devel

（如不選安裝包，安裝過程會提示要求選擇安裝包）

clearpart --all  --initlabel  此命令可避免 手工清除磁盤數據

# Disk partitioning information    
part /boot --fstype="ext4" --size=500    
part / --fstype="ext4" --size=10000    
part swap --fstype="swap" --size=2000    
part /data --fstype="ext4" --grow --maxsize=1 --size=1

磁盤分區如要使用LVM 可手工修改配置文件

part /boot --fstype="ext4" --size=500    
part swap --fstype="swap" --size=1000    
part pv.01 --size=1 --grow    
volgroup vg_test --pesize=8192 pv.01 (要加上—pesize 參數 指定pe大小）    
logvol / --vgname=vg_test --size=8192 --name=lv_root    
logvol /data --vgname=vg_test --size=1000 --name=lv_data
